Riemannian Foliations and the Topology of Lorentzian Manifolds
Kordian Lärz
A parallel lightlike vector field on a Lorentzian manifold naturally defines a foliation of codimension one. If either all leaves of are compact or…

On the normal holonomy representation of spacelike submanifolds in pseudo-Riemannian space forms
Kordian Lärz
In this paper we study weakly irreducible holonomy representations of the normal connection of a spacelike submanifold in a pseudo-Riemannian space from. We associate screen repres…

A class of Lorentzian manifolds with indecomposable holonomy groups
Kordian Lärz
We consider a class of -bundles whose total space admits a nowhere vanishing recurrent lightlike vector field with respect to a Lorentzian metric. This metric can be modifie…
